Kernel for the beagleboard.org boards

usage

3.12 patchset:

git checkout origin/3.12 -b 3.12
./patch.sh

To build it:

cd kernel
cp ../configs/beaglebone .config
make ARCH=arm LOADADDR=0x80008000 uImage dtbs
make ARCH=arm LOADADDR=0x80008000 modules

copy over zImage, uImage, am335x-bone.dtb, and am335x-boneblack.dtb to /boot (on the large ext4 partition) install modules in /lib/modules/ (on the large ext4 partition)
